Note, that if you're doing this to have multiple installations of
MacPorts, you'll probably want to pass other "prefix" changes as well.
I used something along the lines of:
--prefix=.../macports/development/macports/
--with-tclpackage=.../macports/development/tcl/
--with-applications-dir=.../macports/development/Applications/
--with-frameworks-dir=.../macports/development/Frameworks/
--with-ports-dir=.../macports/development/ports/

And you'll still have to contend with things like launchd plists that
want to install under /Library

Or, you may be content with just using "--prefix".

MacPorts should be the only thing writing to /opt/local anyway, why
exactly do you want to install to a different prefix? I ask because
there may be a better solution to your problem.
